Yes it's possible to bulk edit products for your custom field '_text_field'
(as in your linked question/answer).
You can add this custom field at the beginning or at the end of edit page.
- For the beginning you will use this hook:
woocommerce_product_bulk_edit_start
- For the end this one:
woocommerce_product_bulk_edit_end
The code (the custom field is at the beginning here):
// Add a custom field to product bulk edit special page
add_action( 'woocommerce_product_bulk_edit_start', 'custom_field_product_bulk_edit', 10, 0 );
function custom_field_product_bulk_edit() {
?>
<div class="inline-edit-group">
<label class="alignleft">
<span class="title"><?php _e('T. dostawy', 'woocommerce'); ?></span>
<span class="input-text-wrap">
<select class="change_t_dostawy change_to" name="change_t_dostawy">
<?php
$options = array(
'' => __( '— No change —', 'woocommerce' ),
'1' => __( 'Change to:', 'woocommerce' ),
);
foreach ( $options as $key => $value ) {
echo '<option value="' . esc_attr( $key ) . '">' . $value . '</option>';
}
?>
</select>
</span>
</label>
<label class="change-input">
<input type="text" name="_t_dostawy" class="text t_dostawy" placeholder="<?php _e( 'Enter Termin dostawy', 'woocommerce' ); ?>" value="" />
</label>
</div>
<?php
}
// Save the custom fields data when submitted for product bulk edit
add_action('woocommerce_product_bulk_edit_save', 'save_custom_field_product_bulk_edit', 10, 1);
function save_custom_field_product_bulk_edit( $product ){
if ( $product->is_type('simple') || $product->is_type('external') ){
$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;
if ( isset( $_REQUEST['_t_dostawy'] ) )
update_post_meta( $product_id, '_text_field', sanitize_text_field( $_REQUEST['_t_dostawy'] ) );
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
This code is tested and works. You will get this:
